Howdy. If you haven’t already tried making a sub kick, I recommend giving it a go. It’s really easy.
I first tried with a crappy stock 6″ car stereo speaker with a paper cone and the result was poor. Which made sense because they never produced much bass and never handled high volumes from what I remember.
Luckily I had some fancy Boston acoustics car speakers in my cupboard that I never got around to installing so I figured I’de give them a go. Well the results were really good. It did exactly as I had hoped. Nice round fat bass tones. I guess that’s what these types of speakers are made for (big thumping car stereos) so give it a go if you have some or buy a second hand one. (I think 6 is the most popular size for sub kicks but some people use 7 or 8 inch too)
It might give you a bit too much level so u can buy a inline attenuator (pad) from hosa or similar. Other than that all u need to do Is connect an xlr lead to the speaker terminals but switch positive and negative around. And pop on a male xlr connector. U can just plug the xlr pad in if u need it. Anyway that might have made sense to u. If not just ask me a question.
The one on the left in top pic is the good one. As you can see directly above the crappy paper cone one sticks to the mic stand by magnetism which is nice but unfortunately the good boston one does not (probably the type of magnet or distance or some other reason) so u can make a stand by using a snare stand (which works well and looks cool) or by being crude like me and sticking the damn thing on to the overhead mic stand with tape. :-). It didn’t seem to effect the sound quality.
